# Windows 下安装

zookeeper 下载地址为: [https://zookeeper.apache.org/releases.html](https://zookeeper.apache.org/releases.html)。

选择一个地址点击版本下载：

下载后解压:

![](https://hexo-img.obs.cn-east-3.myhuaweicloud.com/img/202210170937469.png)

将 conf 目录下的 zoo_sample.cfg 文件，复制一份，重命名为 zoo.cfg:

![](https://hexo-img.obs.cn-east-3.myhuaweicloud.com/img/202210170937492.png)

在安装目录下面新建一个空的 data 文件夹和 log 文件夹:

![](https://hexo-img.obs.cn-east-3.myhuaweicloud.com/img/202210170937687.png)

修改 zoo.cfg 配置文件，将 dataDir=/tmp/zookeeper 修改成 zookeeper 安装目录所在的 data 文件夹，再添加一条添加数据日志的配置 (需要根据自己的安装路径修改)。
